Patent JP-H0276747-A (JP)
Title: Manufacture of spring charge-type dot head
Inventor: KASUGA TATSUYA
IPC: B41J2/235
Filed: 1988-09-13
Abstract: PURPOSE:To make a distortion energy for a leaf spring constant during the attraction of an armature regardless of the warp of the leaf spring by aligning the height of the fabricated part of a section where the leaf spring is fixed to the armature, bending the leaf spring in a state where the armature is attracted and held in place and fabricating the attractive surface of the armature in such a state to make the attractive surface the same plane as a side yoke surface. CONSTITUTION:A motor 7 is driven to rotate a rotary table 6 to which a drive system unit is fixed and a whetstone 8. In this state, the whetstone is allowed to come in contact with a section where a leaf spring 3 is fixed to an armature to polish the leaf spring. The polished section where the leaf spring 3 is fixed to the armature of the leaf spring maintains the size from the top of a spring stopper plate 4 which is a reference plane, entirely unchanged regardless of the warp of the leaf spring 3. By this fabrication technique of the leaf spring 3, the bending amount of the leaf spring 3 fixed to the drive system unit is equal across the entire length of the former. In this state, the armature is obliquely fabricated and the attractive surface of the armature is finished so that it becomes the same plane as a side yoke surface 13.

Title: Apparatus for controlling stop at predetermined position
Inventor: YATSUSU YASUAKI
IPC: H02P3/06
Filed: 1988-09-13
Abstract: PURPOSE:To prevent transient oscillation and to stop a device steplessly by imparting a stop position command and an idling speed command to a motor, detecting the position of the motor, obtaining a correcting signal based on the deviation from the instructed position, and driving the motor. CONSTITUTION:A stop position signal D is instructed from a stop position command circuit 2. At the same time, an idle speed command A is outputted from a speed command circuit 1. An actual position signal F is outputted from a position detector 7 which is linked with a rotating motor 6. The difference between the signal F and the stop position signal D is inputted into an automatic position adjusting device 3, and a signal B is outputted and inputted into a signal processing circuit 8. The signal processing circuit 8 outputs a speed command signal E based on the signals A and B. The speed of the motor 6 is reduced through a driving device 5. When the difference between the actual position of a load and the instructed stop position becomes within a specified deviation, speed control is changed into position control. In this way, transient oscillation is prevented, and stepless stopping is performed.

Title: Crosstalk compensating circuit in switching device
Inventor: SAITOU TOSHIO
IPC: H03F3/181
Filed: 1982-12-25
Abstract: PURPOSE:To improve the crosstalk characteristic as a switching circuit by applying a signal not selected to an inverting input of an amplifier by means of a capacitive coupling in a circuit switching a broad band signal so as to compensate the crosstalk characteristic of the switching device itself. CONSTITUTION:When an input terminal 1 is selected, the effect of a capacitor 10 is not given by decreasing sufficiently the impedance of the circuit. Further, a signal applied from an input terminal 2 causes crosstalk through a bus of electrostatic coupling from a contact Y of the switching device to a common contact Z. The signal applied from the input terminal 2 is inputted to a noninverting input of the amplifier 4 by the capacitor 11 at the same time. Further, the electrostatic capacitance of the capacitor 11 is made almost equal to the value of the electrostatic capacitance between the contact Y and the common contact Z, allowing to eliminate unnecessary crosstalk signal appeared at an output terminal 9. Thus, the crosstalk characteristic of the switching device itself is compensated and the crosstalk characteristic as the switching circuit is improved.

IPC: F26B3/02
Filed: 1989-09-06
Abstract: PURPOSE:To obtain a high drying efficiency at a low cost by feeding air in a turbulent state to an empty can to the surface of which water adheres. CONSTITUTION:An empty can 10, to the surface of which water adheres, is placed on a belt and conveyed in a cleaning process. The empty can 10 so conveyed passes under a plurality of vortex flow producing devices 30. Thereupon, a fan device feeds air from a portion between corrugated sheets 31, 32 toward the belt 20, in the vortex flow producing device 30. The air becomes turbulent as a certain type of turbulence passing through between the corrugated sheets 31 and 32, and flows downward to the surface of the empty can 10. Once reaching the can surface, it disturbs the air flow and effectively dries the water adhering to the surface of the empty can 10. Hereby the corrugated sheet 31, which includes a plurality of crests 31a and valleys 31b formed parallely to one diagonal line therebetween, is disposed vertically separated away from the belt 20 and directed in its surface direction vertically. The corrugated sheet 32, likewise the corrugated sheet 31, includes crests 32a and valleys 32b formed perpendicularly to those of the corrugated sheet 31.
